Md. Masd Rana Hello Mr. Masd Rana Thank you for your message. Heat stress is a significant economic threat to poultry industries, especially during summer and affecting the growth performance. Although the environmental variations are unable to control, Gano-met® can provide suitable precautions to protect the animals. ...

Studies in the past decade have shown that Cordyceps militaris has multiple pharmacological functions, including anti-oxidant, anti-inflammatory, antimicrobial, anti-tumor, and anti-angiogenic activities and immunopotentiation ability. The chemical structure of cordycepin is similar to that of adenosine. Cordycepin can be used as a nucleotide during RNA synthesis, which leads to premature termination of chain elongation because of the absence of oxygen in the 3′...

Introduction Protein is a major component of animal tissues and products. Thus, adequate intake of dietary protein is essential to optimise growth, production performance, and feed efficiency in poultry. Soybean meal is most commonly used protein source and used around 20-30 % in poultry feed. Now days protein feed ingredients like soybean meal are consistently increasing in cost; so protein has become one of the most expensive nutrients in poultry diet. After feed consumed by...

Introduction The influence of seminal plasma on sperm storage may vary among species. Its removal is recommended in the majority of semen cryopreservation protocols of species such as caprine in order to ensure maximal sperm viability [1], but it isn’t entirely recommended in other mammals (e.g. ovine; [2]). Mammalian seminal plasma may contain factors that influence resistance of sperm to cold-shock damage and may prevent cryoinjury [3–5]. Conversely, detrimental...

INTRODUCTION Poultry and poultry products represent a popular choice of protein in the United States, with increasingly high consumption rates over the past years (Zhang et al., 2018). Poultry meat has surpassed both pork and beef in per capita consumption in the United States (USDA Economic Research Service, 2020). With this increased consumption of poultry and poultry products, there is a significant concern for contamination, thus impacting public health. Salmonella and...

INTRODUCTION Amino acids (AA) and crude protein (CP) intake during the rearing phase in broiler breeders have demonstrated to affect body composition and reproductive performance in the laying period (Joseph et al., 2000; Ciacciariello and Tyler, 2013; van Emous et al., 2013, 2015a, 2015b). Modifications of these nutrients added up to the adjustment of feed allocation may alter BW (van Emous et al., 2013; Soumeh et al., 2018), organ development (Lesuisse et al., 2017), egg...

The majority of pig and poultry diets are composed of about 70% maize or wheat, 20% soybean meal or other similar protein sources, and 10% micro-ingredients. Although this is a simplification, it illustrates the point that the majority of pork, poultry, and eggs are produced using a limited range of ingredients. In addition, it is important to note that feed cost is about 60-70% of overall production cost. And, as feedstuff prices continue to be prohibitively high, with detrimental...

Dear Luis, in the last few years, we had a close look at the quality of different protein-rich feed ingredients and we developed NIR calibrations which can now be used locally to estimate the quality. The reactive Lys to Lys ratio is a good indicator for over-processing and it works in Soybean products, but also in Canola Meal and DDGS. In Canola it might be worth to check in addition the levels of Glucosinolates and Erucic acid. It should be low, but it's better to check it. All...

Introduction Conventional systems (battery cages) lead commercial egg production worldwide due to their reportedly efficient disease prevention processes (WHILEY; ROSS, 2015). However, shifts in egg consumption have drawn attention to potential animal welfare issues and generated demand for alternative laying systems with improved hen wellbeing. In this way, free-range systems could be an ideal choice for egg production and hen welfare (JONES at al., 2012); however, despite...

I. INTRODUCTION Phosphorus (P) is a critical nutrient for growth and structural integrity of growing animals. Nutritionists generally tend to use a significant margin of safety while formulating commercial diets to avoid any deficiency symptoms. A large variation appears to exist in P requirement estimates/recommendations for broiler chickens across different sources; e.g. summarizing some selected references, Table 1 shows the highest vs. lowest estimates to differ by...

INTRODUCTION Methionine (Met) is often considered to be the first limiting amino acid in modern broiler diets. Synthetic Met has been commercially available for animal feed since the 1950s and is routinely included in modern poultry diets. Whilst studies on Met requirements, based on growth performance parameters are not novel, understanding the impact of dietary Met supplementations on apparent digestibility and plasma concentrations of amino acid is important in conventional...

I. INTRODUCTION Optimum BW is an important consideration in achieving early maturity, high productivity and uniformity in laying hens (Lacin et al., 2009). Parkinson et al. (2015) noted that it was common for Australian flocks to have an average body weight (BW) 100-300 grams above the breed standard weight (BSW). This higher BW is indicative of bird obesity and is associated with the production of excessively large eggs with consequently lower eggshell quality and...

I. INTRODUCTION True sustainability was defined by the World Commission on Environment and Development (Brundtland Commission, 1987) as “the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs”. Sustainability is a concept with multiple facets including, environmental (which includes both the demand for resources and environmental pollution), ethical (welfare and social conscience), economic and...

I. INTRODUCTION Xylans, together with β-glucans and cellulose constitute non-starch polysaccharides (NSP) that cannot be fully degraded by monogastric animals (Cowieson at al., 2008). NSPs have an antinutritive effect by increasing the viscosity of the intestinal digesta (Choct and Annison, 1992; Craig et al., 2020). This increase in digesta viscosity causes an impairment of nutrient bioavailability and a decrease in metabolizable energy, lowering the overall performance of...
